Indoor Air Quality

Breathe easy—Duramax installs whole-home air-quality systems that filter, sanitize, and balance humidity for cleaner, healthier air 365 days a year.

Indoor Air Quality Solutions

Wildfire smoke, mold spores, pet dander, and coastal humidity can all sneak into Portland-area homes, aggravating allergies and driving up energy use. Duramax Heating & Cooling Inc. delivers turn-key indoor air quality (IAQ) upgrades that capture 99.97 % of airborne particles, neutralize germs, and keep humidity in the comfort zone—all without sacrificing efficiency.

Our NATE-certified IAQ specialists evaluate ductwork, airflow, and pollutant sources, then design a custom package of HEPA filtration, UV-C germicidal lights, and smart humidity control. We integrate these systems with your existing HVAC equipment, file every rebate, and train you on simple filter changes so cleaner air becomes effortless.
